Scientists from the American College of Physicians have identified the health benefits of black tea, such as reducing the risk of premature death. Study published In the Annals of Internal Medicine.
The researchers used data from the UK Biobank repository of medical and genetic information on the health of 500,000 people who commonly consume black tea.
People aged 40 to 69 completed a basic questionnaire about their life and health between 2006 and 2010. Of these, 85% reported that they regularly drank tea and 89% reported that they drank black tea. Over an average of 11 years of follow-up, those who drank at least two cups of tea a day had a 9-13% lower risk of premature death.
Remarkably, the effect was clear regardless of whether milk or sugar was added to the tea, what temperature the tea was at, and genetic differences in caffeine metabolism among participants.
According to scientists, drinking tea reduces the level of oxidative stress (a sharp increase in oxidative processes in the body with insufficient functioning of the antioxidant system) and can improve the function of endothelin – cells lining the inner surface of the blood and lymphatic cells. ships.
